This is a long sutta, I don't think it is the one you are searching for, but which touches on the topic:

MN 136 Maha Kammavibhanga Sutta: The Greater Analysis of Action [....................]"In the case of the person who abstains from taking life... & holds right view [yet] with the breakup of the body, after death, reappears in a plane of deprivation, a bad destination, a lower realm, hell: Either earlier he performed evil action that is to be felt as painful, or later he performed evil action that is to be felt as painful, or at the time of death he adopted & carried out wrong view. Because of that, with the breakup of the body, after death, he reappears in a plane of deprivation, a bad destination, a lower realm, hell. But as for the results of abstaining from taking life... holding right view, he will feel them either right here & now, or in the next [lifetime], or following that.

"Thus, Ānanda, there is action that is ineffectual and apparently ineffectual. There is action that is ineffectual but apparently effectual. There is action that is both effectual and apparently effectual. There is action that is effectual but apparently ineffectual."http://www.accesstoinsight.org/tipitaka ... .than.html

---The trouble is that you think you have time------Worry is the Interest, paid in advance, on a debt you may never owe------It's not what happens to you in life that is important ~ it's what you do with it ---

Bhikkhus, if you develop and make much this one thing, it invariably leads to weariness, cessation, appeasement, realization and extinction. What is it? It is recollecting the Enlightened One. If this single thing is recollected and made much, it invariably leads to weariness, cessation, appeasement, realization and extinction.Anguttara-Nikaya: Ekanipata: Ekadhammapali: PañhamavaggaVSMVMMWBBTBHTWTBTMy Page
